- Gas HEATER.

Application led April 14, 1926. Serial No.` 102,014.

This invention appertains generally tor new and useful improvements in heating appliancesy and has more specific reference to a novel and simplified gas heater.

The primary object of the present invention is to provide such a' gas heater adapted primarily for use in the heating of houses andthe like and which is to -be positioned beneath the Hoor of the roomfof the house 4or the like in'which it is installed.

Another object of the present invention isv vthe provision of such a gas heater provided wlth a maximum heat radiating surface.

Another object ofthe present invention isv .f to" provide such a gasheater having asso-y ciated therewith a new and novel type of burner together f with improved means for lighting the same.

A further object of the present invention is the provision of such a gas heater includinga casing and a plurality of heat radiatingy baffle plates together withnovel vmeans for Supporting the said plates whereby they may be moved exteriorly of the casing when it is desired to light the burner.

A still further`A object of the present invention is to provide sucha gas heater which Cab while simple and ycompact in construction is nevertheless strong, sturdy and durable; one which is cheap to manufacture and can be placedon lthe market at a reasonable fig` ure,-and onev which will accomplish all of the objects and perform all of the functions claimed; y e y f With these and numerous other objects in view, the invention resides in thel novel coninvention showing the cover in raised position. f

Figure 2 is a top plan view of the burner. Figure 3 is a sectional view taken 3 3 of Figure 2. Y l i Figure 4 is a vertical central sectional view taken through the improved heater.

Figure 5 is a top plan view thereof partially broken away. l

on line Reference now being had more i particularly to the accompanying drawings wherein t for the purpose of illustration has been disclosed a preferred embodiment of the present invention, it willpbe noted ythat the same em` bodies in its construction a casing 10'l which y t may be of any desired `shape and size and' which has been shown Vin the drawings as of substantially square'. formation. This casing "10 is adapted to be positioned beneath ther floor of the 'room of the house or the like 5' which is to be heated andis preferably supf i ported in position by means vof the right angularly directed flanges 11 formed on the upper edges of the side and end walls of the casing.

y Leading t adjacent the bottom wall 12 thereof vis an air pipe 13 which is secured at its inner end rvto the angular coupling 14, which coupling is in turn secured to the lower end of the ceni trallyLdisposed depending nipple 15 of the into the casing l0 immediately' burner generally designated bythe reference e numeral 16 and comprising in its constru`c' tion a bottom wall 17 the annularjsidev wall separate and spread the gas *fla-me.

Also leadinginto the casing l0 'adjacent to" and above the air pipe 13 is the main gas pipe '22 leading froma suitable source of 'supply' `and having its inner end secured to 'the horizontal leg 23 of the burner nozzle 24 carried by the depending nipple `15'and pro#` vided with the restricted terminal vopening 25,v Positioned Within the length of the main* i gas pipe 22 is a vertically disposed auxiliary gas pipe 26 and disposed in the main gas ypipe 22 lat opposite sides of the auxiliary gas I pipe 26 is the main valve 27 and the saiety valve 28. The upper end of the auxiliary gas pipe 26 isl directed laterally towards'the burner 16 and'carries the nozzle 28infr'ont of which is disposed a fire starting fuse`29,

said fuse being suspended from the bracket arm 30 swingably associated as at 31 with the Vnozzle 28.

Disposed within the auxiliary gas pipe 26 is a valve 32. n f

The firestarting fuse 29 is of any conventional or preferred construction andis off that type which Will be lighted by the heatl of the gas. That is to say, whentheval've 32 is openedfand'gas is permittedto ow e throughthe nozzle 28, the said gas contact--` ing with` the `fuse 29will cause the same to burst intol'ameand this flame will, in turn,

light the gas flowingv from the nozzle 28.

Theflighted gas from the nozzle 28 will then light ,the'burner 16 asL will more 'fully `here-` v.inafter appear. there is provided an automatic means for' Thus, it will be seen that lighting the burner 16 so that the use of matches and the like is eliminated.

` .'The.,upper ',edge of one of the side or endv kwal'lSfol-` the casinglO' is Aprovided withl the spaced'iiolled hinge sections 3'3'radapted tore-` he'rebetween the lcomplemental' hinge 35,'Qa5suitable pivt pin `36l extendingthrough the.

said wall/38being bent inwardly and anguflarly asat. 391.to7provide a recessfor the receptionl of,Y the yfire starting fuse 29. andl the 'bliicketarmg30.

The valve 32 is then closed and the cover 35 is also su-bsequentlyy closed. The gas issuing from the burner- 16 will heat the baffle plates 48` and 50 and the heat from these baille plates willthen be. f Vsubsequently 'thrown through the apertureid cover 35 into-the room in whichLthe-,appliance isinstalled.
